omar Posted February 24, 2020 Share #1 Posted February 24, 2020 I updated my DSM a while back and updated my usb boot drive for xpenology. This for some reason stopped my Gen8 server from booting from usb, didnt matter which port I used. I think the reason is due to the fact I was not on win10 when I first created the usb When you install Win10 you will be installing it with UEFI So when you create your bootable usb on Win10, I guess it does it so its compatible, so the drive is formatted for GPT drive I think since the Gen 8 is using an old BIOS, it will only boot under a usb drive formatted for MBR So to get around this you will need to use rufus to create the bootable usb When you load the iso file for xpenology, you'll see the Partition Scheme is GPT, and greyed out, so you cant change it. Two ways to change it, Check the List USB drives, this may then flip it to MBR Download win10 installation iso from Microsoft Select this win10 iso as if you are going to make a bootable win10 usb installation drive Then you will be able to change GPT to MBR Then change iso to xpenology Then create bootable usb as normal Win32DiskImager does not give you the option to select GPT or MBR partition schemes. So my guess it uses the system default. So if you have win10, it is most likely GPT Hence the USB is GPT, and the server will not boot from it. See this image to see check Should work on other servers which have similar issues It's just the BIOS is too old for GPT I guess. Quote Link to comment Share on other sites More sharing options...
